My invention relates to improvements in "eed regulators and its object is to provide the same with improved means for accurately measuring and feeding the ingredients forming the concrete which usually consists of cement, sand and gravel or broken stone and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure 1. is a side elevation of a device embodying my invention, Fig. 2. an end elevation viewed from the discharge end of the machine; Fig. 3. an end elevation viewed from the front end of the machine, with a portion of the motor removed; Fig. 4. an enlarged vertical section of the feed mechanism; Fig. 5. a plan view of the same with the mechanism outside of the hoppers omitted.

Like numbers refer to like parts in all of the figures.

1 represents any convenient motor, preferably an internal combustion engine; 2, 2 and 2 represent a series of three hoppers to receive sand, cement and gravel; 3 represents the mixer, 4 is the driving shaft of the device journaled in the middle hopper and having a constant rotary motion, preferably by means of a sprocket wheel 5 fixed thereon and connected by a chain 6 to a sprocket wheel on the engine shaft. 7 and 8 are sprocket wheels respectively on the shaft 4 and the shaft of the mixer and connected by a chain 9, whereby the mixer is driven from the shaft 4. 10 is an agitator shaft near the bottom of the hopper 2 Specification of Letters Patent.

On the shaft 4 is a loose pinion 11 connected to the shaft by means of a manually operated clutch 12. This pinion engages a gear 11 fixed on the shaft 10 to drive the same. On the opposite end of this shaft 10 is a crank 11 and operated by this gear and crank are connecting rods 13 pivoted thereto at one end and at the other end attached to a sliding frame reciprocated thereby. The sides 14 of this frame slidably embrace the sides of the hopper and the ends 14 of said frame are secured to the sides 14 by flanges 14 and constitute the lower parts of the outer walls of the respective hoppers, the upper parts 15 of said walls being detached from the side walls and pivoted to the ends 14 and horizontally reciprocated thereby and held from horizontal movement between transverse rods 16 and 18 between which these upper parts oscillate and slide when moved horizontally at the lower edge by the frame. These walls 15 thus alternately turn from vertical to horizontal position and back again. Extending across the middle of this frame is a bar 20 which oscillates below the middle hopper 2 being attached to and carried by the sides 14 and traversing the surface of the portion 17 of the bed plate. This frame 14 slides on a bed plate 17 extending beneath all of the hoppers, the middle portion 17 of this plate being spaced apart from the end portions leaving two openings 19 at the respective sides of the middle hopper and between it and the end hoppers. Transverse inclined walls 22 converging downward forma middle hopper 2 and oppositely inclined walls 23 extending therefrom formthe inner walls of the respective outer hoppers 2 and 2 the space between the lower part of these walls 22 and 23 being opposite the openings 19 in the bed plate. These walls 22 and 23 are also spaced apart from the bed plate at the lower edges and the hopper 2 is provided with vertically adjustable gates 21 extending below the walls 22 to regulate the feed of the cement, and the walls 23 are each provided at the lower edge with vertically adjustable brushes arranged opposite the portions 17 of the bed plate whereby the feed of the sand and gravel is regulated and any solid of considerable size therein permitted to pass without stalling or breaking the machine.

In operation, the sand is placed in one of the end hoppers, the cement in the middle hopper, and the gravel or broken stone in the other end hopper. By engaging the clutch, the shaft 10 will be rotated and through the connecting rods 13 will impart a reciprocating movement to the frame 14. The transverse ends 14 of the frame will thus move toward and away from the brush 24:, each end thus crowding the sand and gravel under the respective brush and discharging the same through the respective opening 19. The

higher these brushes are set, the more rapid will be this discharge. The lower portion of the walls 15 moving toward the brush presents an increasing backward inclination of this wall whereby the material that does not escape under the brush will slide up on this inclined surface and thus relieve the pressure against the brush and wall 23. As the frame recedes the wall 15 rises to vertical position and thus prevents the collecting of the material on the same or clogging in the hopper. This movement of the end wall of the hoppers thus materially facilitates the operation of the device. At each movement of the frame the bar 20 traverses partially across the middle portion 17 of the bed plate and thus pushes a portion of the cement out beneath the respective gate 21 and discharges the same into one of the openings 19. Thus each discharge of a quantity of sand or gravel is followed by the discharge of a quantity of cement through the same opening 19. This alternate action consists in mingling the ingredients evenly.

What I claim is:

1. A feed regulator comprising a fixed bed plate, a hopper above the bed plate having one wall spaced apart from the bed plate and having its opposite wall horizontally reciprocable along the surface of the bed plate at the bottom and held from horizontal movement at the top, and means for reciprocating the bottom of said wall.

2. A feed regulator comprising a bed plate, a hopper above the bed plate and having one wall spaced apart therefrom, a horizontally reciprocable frame having one end forming the ower part of the op osite wall of the hop per and traversing the ed plate and an upper part to said last named wall pivoted to said end of the frame and carried thereby,

means for holding the upper part of said wall substantially stationary at the top and means for reciprocating the frame.

3. A feed regulator comprising a bed plate, a hopper above the bed plate and having one We 1 spaced apart therefrom and provided with an adjustable brush and an oppoupper part held from horizontal movement, and its lower part reciprocable along the surface of the bed plate, and means for recipro- 7 eating the lower part of said wall.

4. A feed regulator comprising a bed plate, a hop er having side Walls extending to the bed p ate and one end wall spaced apart therefrom, a reciprocable frame having an end traversing the bed plate and forming the lower part of the other wall of the hopper, and an upper part to said wall pivoted to said end at the lower edge and slidable between transverse rods near its upper edge.

5. A feed regulator comprising a series of three hoppers spaced apart at the bottom, a bed plate below all of the hoppers and having two openings opposite the spaces between the hoppers, the transverse walls of the middle hopper and the inner walls of the end hoppers being fixed and spaced apart from the bed plate, a frame having its ends forming the lower part of the outer Walls of the end hoppers and slidable on the bed plate, movable walls each pivoted at the lower edge to the respective end of the frame and held substantially stationary at the upper edge, and a bar attached to the frame and reciprocable on the bed plate below the middle hopper.
